tcpm/anx7447.c: use chip internal timer to generate HPD IRQstabilize-sylas-13019.B-master
Anx7447 has 2 ways to generate HPD IRQ:
1): internal timer delay ~750ms.
2): outside timer delay(configured by EC anx7447.c).
Some board didn't have accurate timer cause method #2 cannot be used,
this patch change the default policy to method #1.
